Please learn to use code boxes, without code boxes, I am not even going to try to read all of that, others might, but it is better with code boxes. Also, What OS are you actually using ? Version, etc. Beyond that, there just is not enough details to be able to help much,...Where did you get this "proxmox" ? How it was installed ? and on what ? Looking at some info, I see it could be on Debian Wheezy, but then again, it could be installed on Debian 8 (jessie), or Debian 9 ,.... ???

Tanks Garry. I edit my question.I add that in the output of dmesg for the device block 253:10

Proxmox VE is a complete server virtualization management solution based on Debian.

Anyway, if you look at the above Debian wiki link, you will see a list of resources, including : https://forum.proxmox.com/ There is nothing wrong with asking here, but I don't think you will get much help here, especially on such a old version. I think you have a better chance of getting some help at the proxmox forum, there might even be members still using this version. I don't know myself, since I have never used proxmox, all though I did use Debian 6 for some time, several years ago, in fact that was the first versionof Debian I used. Probably the best thing to do, back up all of your data and install fresh, with the current version of Proxmox: https://pve.proxmox.com/wiki/Installation
